Outside of US, seeing imperial units is pretty rare. Even UK uses metric for most purposes.

If I am not wrong, US is one of those very rare countries (probably just 2?) which doesn't have measurement units codified as a binding standard, allowing NIST to maintain/allow several different, coexisting measurement systems (for e.g. some measurements are reported traditionally in meters e.g. fabric, metals, rod lengths, but several commercial entities also use foot & yards in their product specifications, even if they are derivatives. This is not the norm usually)
